[PATCH 12/16] wireless: mediatek: convert tasklets to use new tasklet_setup() API
From: Allen Pais
Date: Mon Aug 17 2020 - 05:09:12 EST
From: Allen Pais <allen.lkml@xxxxxxxxx>
In preparation for unconditionally passing the
struct tasklet_struct pointer to all tasklet
callbacks, switch to using the new tasklet_setup()
and from_tasklet() to pass the tasklet pointer explicitly.
